Please help Pat is filling a bathtub. She lets the water run for two minutes, which fills the tub one-quarter full. She then turns off the water to answer the telephone. When she returns 3 minutes later, she turns the taps fully open to finish filling the tub three quarters full, which takes another 3 minutes. She gets into the tub. After a 10 minute bath, she pulls the plug, and the tub drains in 5 minutes. Sketch a graph of the water level in the tub from start to finish. Remember to label the axes and to use appropriate scales.
